Threatened Puget Sound steelhead face many challenges on their migration, including infrastructure barriers like the Hood Canal floating bridge.

As the Earth’s climate continues to warm, researchers predict wild animals will be forced to relocate their habitats — likely to regions with large human populations — dramatically increasing the risk of a viral jump to humans that could lead to the next pandemic.

Microplastics are a pathway for pathogens on land to reach the ocean, with likely consequences for human and wildlife health, according to a study from the University of California, Davis.

Wildlife watchers generally welcome species that have arrived in the UK due to climate change, new research suggests.

Red tides, or harmful algal blooms, can cause low oxygen levels in coastal waters.

Researchers led by Göttingen University study bee behaviour and bean harvests

However, in small quantities it can be quite sustainable, shows a study by the University of Bonn

An international research team use a global sampling of seawater to reveal which tropical reef fish occur where. 

Non-native bullfrogs and sunfish species, introduced for consumer and sport purposes, are known to alter ecosystems and hinder native amphibians and fish in the Pacific Northwest highlands.

Geological evidence shows the reef system has a history of demise and resilience.
